I have the smallest Oticon Own and the batteries are very hard to remove as Oticon’s battery case has them nearly locked in. So I purchased this magnet pen on Amazon and it makes remove the battery very easy:

Be assured, I am not a vendor of Amazon and not benefiting from this in any way other than sharing what worked for me. Those with bigger hearing aids probably will not relate to the difficulty of removing a battery, but for small hearing aids, I know many will relate. You can also use this to put a battery in, but I find it to be much faster if I use my fingers.
